Autism gut issues, the gut-brain axis, and bioregulators come together in this conversation with Dr. Grace Liu, PharmD. Grace explains why she approaches the gut and the brain as one interconnected system rather than working through them in sequence, what peptide bioregulators are and how they differ from signaling peptides, what the research actually shows, and why highly reactive children need a very different clinical lens.
For most families the starting point is not theory. It is constipation, diarrhea, extreme food selectivity, and the behavior changes that seem to track alongside them. Grace talks through the microbiome picture underneath those symptoms, why some children react to almost everything including their own probiotics, and what she watches for when nothing is tolerated.
She is also direct about the limits of the evidence. Much of the bioregulator literature sits outside peer-reviewed Western research, and she says so plainly rather than overselling it. The conversation closes on caregiver health, and why the twenty and thirty year horizon for parents belongs in the same roadmap as their kids.
